Coke, a material made from heating but not combusting coal, is a common fuel source for use in forges and in blacksmithing. Coke is made in the same way as charcoal, in that it is heated to high temperatures, but starved of oxygen to prevent it from burning. This produces a light, porous rock that burns cleaner than coal, with less tar residue.

The degree of change undergone by a coal as it matures from peat to anthracite is known as coalification. Coalification has an important bearing on coal''s physical and chemical properties and is referred to as the ''rank'' of the coal. Ranking is determined by the degree of transformation of the original plant material to carbon.
Coal was important to the Industrial Revolution because it burned hotter than wood charcoal. The additional heat was needed in the boilers that ran the steam engines developed during the Industrial Revolution, according to the United States Department of Energy.
